Sorry for asking the obvious, but it looks like some are thinking that
you should not write a plist file which would "belong" to some running
app.
I really wonder why one would think so. For me, most of the time
preference files are read when the app opens, then again if you ask
the app's preferences, and they are saved when you click "save" over a
change. Of course if you're writing at the very same moment the file
may get corrupt - usually it ends with the beginning of one version
ending with the end of the other version. But this is highly unlikely,
the window to collide would be less than 1/1000 second.
I'm sure those who think it's dangerous are right, maybe it's specific
to Lion, but could someone enlighten me?
Best,
Emmanuel

is it a more general problem with writing any preference plist file?
It's a *potential* problem when writing to any plist file that
belongs to a
running application. It shouldn't cause the damage you're seeing, but
results will vary from no problems, through intermittent problems, to
crashing problems. It's a hack -- sometimes useful, but potentially
problematic.
